TODO

libsigrok

Hardware support

• Clean up device-specific globals in hardware drivers, to properly permit multiple devices per driver: fx2lafw, zeroplus-logic-cube, others(?)
• Chronovu LA8/LA16 driver: support multiple devices properly (currently only one is supported).

Input modules

• Add OLS input module support.
• Add gnuplot input module support (Uwe Hermann).

Miscellaneous

• Check all public API calls to see whether they need an sr_context parameter.
• sr_errno:
  • Most functions should return SR_OK or SR_ERR_* (same for SRD_OK etc).
  • Most backend functions return status as an integer, which is SR_OK if all went well, or SR_ERR_* if an error occurred.
  • However, there is no way to pass any information back as to what went wrong — and this is important for user-friendliness.
  • Perhaps an error code is not enough; maybe something like sigrok_errno(errorcode, "unsupported device") is better.
• Support specifying the firmware directory at runtime.

libsigrokdecode

Major features

• Add high-precision timer to runtc
• Add annotation mime types
• Add annotation metadata (type/value/unit) to allow clients to format the value as the user desires (ASCII/dec/hex/bin/whatever)

Other

• Test/implement support for multiple outputs of one PD, and stacking different additional PDs on those outputs.
• Test/implement multiple inputs support.
• Python exception handling in libsrd: add full traceback support with srd_dbg().

fx2lafw

• Analog sampling: 1-channel, 2-channel, voltage meter
• Trigger pin
• Clock input
• Clock output
• Frequency/pulse counter
• Signal generator
• Fix power consumption during enumeration.
  • Non-LP FX2's consume more than 100mA during enumeration. This is outside of the USB specification
  • Official workaround is to enumerate first as full-speed, then as high-speed. This is overkill for sigrok.
  • Investigate putting the CPU to sleep (except for processing interrupts) until enumerated.

PulseView

• Deduplicate property setting functionality between SamplingBar and DeviceOptions - make SamplingBar a properties container
• Analog interpolation (cosine? sinc? some kind of interpolation filter?)
• Signal overview
• Transition coding

sigrok-meter

• Make the list of measurements look nicer without using too much additional space.
• Add graphs.
  • PyQtGraph looks like a nice graphing library.
    • Works with PyQt and PySide.
    • Pure python, easy to install.
    • Few dependencies: scipy is not required any more in the upcoming version 0.9.9, numpy is already a dependency of the python bindings.
    • From looking at the examples, it seems more than fast enough for our requirements.
  • Pass all samples (not only the most recent one) to the GUI thread and store them there.
    • The packet payload object is currently not thread save.
